Making a Murderer's Steven Avery apparently had his legal team inform his now former fiancee that he wanted to break up.

Avery and 53-year-old Las Vegas woman Lynn Hartman got engaged in late September, but mere days later it was revealed that Avery had broken up with her. Now, according to In Touch, it's been revealed that Avery broke up with her via his legal team.

A legal document acquired by the publication written by Avery's attorney, Kathleen Zellner requests that Hartman stop giving interviews about her relationship with Avery and notes that the engagement is "terminated."

"Please let this letter act as formal notice that Mr. Avery terminated his engagement with you effective October 2," the letter states. "As Mr. Avery expressed to you during your relationship with him, he deems his correspondence and communications with you to be confidential. This constitutes an oral agreement with him."

Zellner requests that Hartman "cease and desist" talking about their relationship in interviews. "Although we believe that you have already breached the oral contract, we will not take any legal action against you unless you continue to violate the terms of your agreement with him."

The letter even demands that Hartman not comment publicly on whether she believes Avery to be innocent or guilty of the 2005 murder of Teresa Halbach, and that she must not sell, distribute or disseminate letters or photographs regarding Avery and their relationship.

Hartman said previously in a People interview that she had envisioned a life for her and Avery after he got out of prison.

"I picture us in the motor home, driving around the countryside - soaking in the hot springs over in Colorado and taking him to places I've been to in this nation he's never had an opportunity to see," she said. "He deserves that opportunity and I can't wait to share that with him."
